This is overcurrent protect for HF driver, can be set with change 0,47R.

hello sir, can you help me? In facebook you said that "‎2,5A peak current limit is 25W RMS for 8R driver, about 300W on x-over input" How to calculate it? Can you teach me? If I change 0,47R to 0,56R What will happen? Thank you very much.

15"horn enclosure

Hello, i found here some 2x12", 2x15" 2x18" and 1x12", 1x18" enclosures, but i did't found any for 1x15" horn/BP enclosure, can You share some of them mr Apex? I'm interested in building two small, but effective subs based on 15tbx100 or 15nw100 or similar from B&C.
Thanks



PS, i think in 4 ohm option of this speakers they would work well with your H900 based power amp.

Bass 2x12inch + mid 4x6inch + 2inch HF driver

Hello. Did you make the box that this speaker is standing on yourself also? I am interested in what the carpet like coating material is called and where it can typically be obtained. I've had no luck searching for it on google.

You don't need 'em, but people who put 40 subs and 10 two way suts over need some advice and suggestions

Im guessing this is a dub bass system, the place where people like to vibe to basslines that are far louder than the mids/tweeters, to save there ears abit

in your b151 design can the drivers be mounted cone out or is there a specific reason for mounting them this way?

There is a reasons (better cooling and larger velocity) for mounting them this way, but drivers can be cone out mounted.

I don't like half of them , I'm not gonna build 'em ! Better building big sealed CONCRETE boxes !! They're gonna rock ! Sure !!
I'm jocking..but ; if there isn't any improvement over the market speakers ,what is the
purpose of a DIYer ? Do you know if there is any difference by putting the top box horizontally or vertically ? I just came to know that an array source can offer a really wide and long soundstage but that after a looooong study and a perfected tecnique.

Take some Valium, brother! Apex is just making suggestions; nobody is forcing you to build anything you don't like. But I think the point of a DIYer is to build somebody's 2000-dollar design and build one that looks and sounds like it but for a quarter of the price. Do you think you are smarter and better equipped to out-design the R&D departments at JBL and EAW??

subwoofer

Dear sir Apex,
I am using your design with 12 inch drivers.Response is very good with 3- way active crossover system.It is driven by your 'quasi amp for beginners' amplifier. I want to know that does it need any subwoofer filter circuit or fine with 3 way active crossover ? Also please suggest me anything suitable to cover front opening of this box.
thanks
sudhir.

You could just cover the area open to the drivers with an acoustically transperent black material, and do the front sloping bits in a wood grain for some contrast...
